Typically, these plants grow from tuberous roots and can thrive in various climates, making them a versatile choice for gardeners.
Characteristics of Alstroemeria

Growing Conditions for Alstroemeria
To grow alstroemeria successfully, it’s essential to provide the right conditions.
Soil Requirements
Alstroemeria thrives in well-draining soil rich in organic matter. Loamy or sandy soils are ideal, but they can adapt to various soil types as long as drainage is adequate.
Sunlight Needs
These plants prefer full sun but can tolerate partial shade, especially in warmer climates. Morning sun with afternoon shade is optimal for preventing leaf scorch.
Watering Guidelines
Alstroemeria requires about one inch of water per week. It’s crucial to avoid waterlogging, as this can lead to root rot. Allow the soil to dry slightly between waterings.
Planting Alstroemeria
When to Plant
The best time to plant alstroemeria is in the spring after the last frost. This allows the plants to establish their roots before the flowering season.
Planting Techniques

- Depth: Plant tubers 4-6 inches deep to ensure stability and moisture retention.
Caring for Alstroemeria
Regular care will keep your alstroemeria healthy and vibrant.
Fertilization
Use a balanced, slow-release fertilizer in early spring to promote growth and flowering. Avoid over-fertilizing, as this can lead to excessive foliage at the expense of blooms.
Pruning
After blooming, remove spent flowers to encourage further blooming and maintain plant health. In fall, cut back the foliage to about 4-6 inches above the ground.
Pests and Diseases
While alstroemeria is relatively resilient, it can be susceptible to certain pests and diseases.
Common Pests
- Aphids: These can be controlled with insecticidal soap or neem oil.
